To all whom it mag concern: 7

Be it known thatI, FREDERICK W. LI NA- KER, a subject of the'King ofEngland, re-

siding at Dubois,in the county of Clearfield and State of Pennsylvania,have yinvented useful improvements in boiler tube cleaners:

The present invention isimore particularly adapted for boilers includingbanks of tubes that have associated therewith baflies that are arrangedadjacent the tubes with the cleaning fiuiddistr'ibuting pipe for thetubes arranged adjacent the free end of the baffle.

The cleaning fluid distributingpipe that is,

arranged ad acent the outer end of the bafiie positioned against thebank of tubes in the chamber adjacent the fire box where the heat in thegases and products of combustion is the most intense, is subjected to acontinued heat from the fire box and soon becomes burnt or otherwiseinjured unless some protectmg means such as a shleld 1s provided Thepresent invention therefore aims to overcome this diflicultyand providesa pro .tecting device for the distributing pipe and nozzles that isassociatedjwith the first bank of tubes that will completely shield thesame when in inoperative position. The device as shown is applied to a'boileithat is known in the trade as the Stirling type and includessemi-vertical and vertical banks of tubes but it is to be understoodthat the invention may as well be applied to horizontal water'tubeboilers without in any manner affecting the gist of the presentinvention.

others that will. appear as the nature of the invention is betterunderstood, thesamecom l panying drawings, and thenclaimed.

With these general objects in view and sists in the novel construction,combination a and arrangement of parts hereinafter more fully described,illustratedin the accom- In the drawings forming a part of thisapplication and in which like designating characters refer tocorresponding parts throughout the several v1ews:-Figure 1 1s across-sectional view of a Stirling boiler with the present invention inoperative position therein.

Fig. 4 is a detail sectional view ofthe distributingpipe, and aportion of an adja- 1 cent boiler tube as shown in Fig. 1,but arranged perpendicularly and illustrating the manner of mounting thecleaning fluid distributing nozzles in the distributing pipe and alsothe protective means for the pipe and nozzle, and, Fig. 5 is a detailperspective View of one of the bearing supports for the u'distributingpipe.

preferably of the rotary or oscillating type and as is usual, the sameis j ournaled at its ends in the sides of the boiler setting. Supportingbearing blocks for the distributing pipe are associated with the pipeand certain ones of the upper row of tubes and by which the distributingpipe is further supported.

The distributing nozzles are carried by the PIPE and are positioned tobe moved to spaces between the adjacent tubes and in their inoperatlveposition are completely removed from the heat zone of the furnace-'while heat refractory material is associated with the supports ornozzles which will prevent the intense heat from the fire contacts ingthe distributing pipe, and means is also associated with the bearingblocks for further protecting the distributing pipe from 'the heat.

.Referring more in detail to the accompanying drawings and particularlyto Fig. '1, there is shown a boiler including the setting 10 havingpositioned therein banks of tubes A, B and C, and associated with thebanks of tubes A and B, are bafii'es D and E. Cleaning fluiddistributing pipes 11 are associated with the banks of tubes B and C.

and may be of any well-known construction in this particular art, butpreferably being of the. rotary type including operating chains 12 as isindicated in dotted lines in Fig. 1. The piping system for feeding thecleaning fluid agent is diagrammatically shown in Fig. 1 and includesthe main supply pipe 13 communicating with the feed pipe 13 which inturn communicates with the branch pipes 14 and each'pipe isiprovidedwith valve control mechanism, whilethe main supply pipe 13 is providedwith a drain cock as is indicated.

The present invention has particular ref- "erence to the cleaning fluiddistributing pipe '15 that is arranged adjacent the bank of tubes A andthe outer end of the baffle D,

this pipe passing through the boiler and being journaled .at its ends inthe sides thereof which is of the usual construction of rotary oroscillating distributing pipe. As

shown more clearly in Figs. 2 and 5, the distributing pipe. 15 isfurther supported intermediate its ends by the bearing blocks 16, theinner ends of which abut the outer end of the bafiie D while the bottomfaces thereof are longitudinally grooved as at 17 for the purpose ofbeing mounted on the upper row of tubes 18 of the bank A. The

aback or rearfaces of the bearing blocks 16 are each provided with strapbearings 19 through which the distributing pipe 15 extend's,'it beingnoted that the bearing blocks are relatively immovablewith respect tothe baffle D and tubes 16 while the distributing pipe is permitted tofreely revolve therein. These bearing blocks will prevent the gases andproducts of combustion from short circuitlng or passing over thedistributing p1pe,

and in order to in'surejthe direct travel of the gases, theouter ends ofthe bearing blocks 16 are provided with tongues orlug extensions 20 thatfurther protect the pipe from the intense heat in the products ofcombustion. v 7

Any. form and number of nozzles may be associated with the distributingpipe 15 and I one of preferred construction is shown in 'detail in Fig.4 and includes a nipple'21 threaded. into the pipe 15 and carries a jetnozzle 22. span the spaces between the boiler tubes 18 are provided withhousings or shields ineluding hub portions-23 mounted on the pipe Theset screw holds the shield relatively immovable withrespcct t0 the pipe15 while the nipple 21 is also threaded through the hub portion 23 whichwill furtherprevent -rela tive movement of the shield and dis-:tributing. pipe. The shields may be made of The sections of the pipethat also} the distributing pipe, this refractory material being ofplastic-cement that is adapted to solidify or may be of any othersuitable material especially adapted for this purpose. Whenthe'distributing pipe is in inoperative position as shown in Figs. 2 and4, the jet nozzle and distributing pipe are completely removed from theheat zone of the furnace and in suchp'osition the heat refractoryfilling 27 is positioned to face the boiler tubes and the heat zone andto form a continuation of the baffle D. Side flanges 28 of circularformfco-incident to the curves ture of the shields are carried. bytheouter sidefaces of thefianges 27 and are adapted further to preventthe escape of the gases and products of combustion from between thetubes and effectually prevent the same from contacting the distributingpipe at any point. i

By reference to Figs. 2 and 4, it will be readily seen that the cleaningfluid distributing pipe in inoperative position is completely removedfrom the heat zone of the furnace and that the bearing blocks carryingthe lu projections and the shields for the distriliuting nozzleseffectively shield the pipe'atthe point Where the same crosses the tubesso as to, eliminate the danger of overheating the sa'me which would bepres ent Without some means for protecting the me. fl Whei1' itis-desired to clean the tubes, the operating chains 12 causes thedistributing pipe-15 to berevolved in the bearing blocks 16' and atwhich time the housings for the nozzles are also revolved with thedistributing pipe to bring the nozzles into position adjacent the tubes,and at this time the re- .fractoryfilling 27 for the housing members ismoved to aposition spaced from the tubes so that the distributingnozzles 22 are exposed andthe jets of cleaning fluid issuing therefrompass over the tubes to remove the coatings of soot therefrom. Thiscleaning operation consumes only a small amount of time and the coolingefi'ect of the cleaning fluid agent will off-set the intense heat of theheat zone. After thepipes have been thoroughly cleaned, the operatingchains cause the'distributing pipe to be revolved in a reverse directionto remove the distributing i nozzles from the heat zone and into theposition shown in Fig. 4 to bring again the distributing nozzles to thepositions remote fromthe heat zone and cause the refractory filling forthe shields to be again exposed for protection. of the pipe and nozzlesas inclicated. In this position, the refractory material 27 in theseveral shield members, forms a continuation of the outer end of thebaflie any suitablematerial as of cast iron or steel D and incombination with the bearing 13o magma blocks 16 and lug projections 20carried thereby, the gases and products of combustion will be entirelyremote from the distributing pipe and nozzles, wherebv the preferred, itis to be understood that the device may as well beapplied to boilers ofother; constructions without departing fromv thespirit and scope of .theinvention as set fortl in the subject-matter claimed.
